Early this year, one day, my Camry's automatic shifter wouldn't budge from Park to Drive until I pressed the Shift Override button. It was a pain in the butt when I needed to make quick starts and manuevers in a parking lot but I got used to it.
Then, over a month ago, after I took it on the freeway one day (I use it for local driving usually) and floored the accerlerator, the shifter somehow fixed itself. I no longer needed to push Shift Override to shift from Park to Drive. I was a happy camper.
Last, week, I was pumping the accerlerator a couple time to test the Camry's accerleration, and then I noticed that when I needed to shift from Park to Drive, I had to push the Shift Override button again! @*@%%!
Do I have loose wires or flaky sensors? I'm hoping I can personally fix it myself since it's an older car but I only have a Haynes Camry manual as the only source of my Camry and Car knowledge and it doesn't have a section on fixing the Shift Override problem.
